The switch allows this preserving of the state using only a toggle on a voltage and thus allowing for a hardware only solution. The switch described herein allows for the use of smaller and less complicated mechanical switches allowing for more compact industrial designs. The switch uses a programmable voltage reference as a 1 bit non-volatile memory cell that is programmed by means of a logic pulse to the device.

Description

2 ELECTRONIC PERSISTENT SWITCH
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application is a non-provisional application claiming the benefit of US.
Provisional Application Ser. No. 62/860,838, entitled "Electronic Persistent Switch,"
which was filed on June 13, 2019, and is incorporated herein by reference in its entirety.
TECHNICAL HELD
[0002] This disclosure relates to an electronic persistent switch.
BACKGROUND
[0003] Voice controlled systems are becoming more and more common and the feature is being included in many different applications around the home. With the prevalence of devices "listening" to consumers the need for a reliable privacy switch is apparent and not easily attainable. Ideally this privacy switch would not allow for any software control, meaning once a user places a device in privacy mode the device would remain in that state until the user physically placed the device back in to active mode.
This state should also be kept through a power outage. In these types of applications form factor and industrial design are also a significant focus as products are marketed to a consumer. Mechanical switches to implement the privacy function tend to be bulky, have a different feel than most buttons and switches currently implemented or are difficult to implement and keep the desired Industrial design.
[0004] Previous solutions required either software controlled switches which lack concrete privacy requirements or latching or sliding switches that will remember the state through the mechanical design.

DETAILED DESCRIPTION
[0010] In certain designs where security and privacy are a concern it may be advantageous to have a switch/ setting that is preserved over a power cycle.
Furthermore in terms of security and transparency it may also be advantageous to have this setting or switch be set without the intervention of any software running on the system.
Two current methods are being used: (1) Non-Volatile memory storage and (2) Mechanical latching or positional switches.
[0011] Traditional methods of using Non-Volatile memory to save settings over a power cycle would use electronic flash memory or require the use of a battery to help store the current state. With current implementations the programming of non volatile storage always requires the use of some programming algorithm thus intervention from some software running on the system.
[0012] The switch described herein allows for the use of an electronic circuit to perform the toggle and persistence functions while simultaneously giving more flexibility to the industrial design and physical switch implementation. The switch allows this preserving of the state using only a toggle on a voltage and thus allowing for a hardware only solution. This solution described herein allows for the use of smaller and less complicated mechanical switches allowing for more compact industrial designs.
[0013] The switch uses a programmable voltage reference as a 1 bit non-volatile memory cell that is programmed by means of a logic pulse to the device. This allows a software independent setting of the state of the privacy switch. This state will remain through power cycles.
[0014] Electrical Switch implementation:
= Uses a programmable voltage reference to generate a 1 bit non-volatile memory to remember the switch state = Voltage reference is "programmed" by means of a voltage pulse and requires no software control = Circuit will set the state of the switch and toggle that state on each press of the button [00151 FIG. 1 shows an example schematic of an electrical switch 100. As an example, the electrical switch 100 may integrated into a client or customer premise equipment (CPE) device having listening and/or video/image capture capabilities, or that is otherwise capable of outputting private user data.
[0016] In response to a button being pressed, a voltage pulse may be generated and output to one or more components of the electrical switch 100. For example, when a button is pressed, a switch 105 may be closed, thereby allowing the voltage pulse to be output to a programmable voltage reference 110 and/or a latch 115. The switch drives a pulse to reprogram the voltage reference 110 to the alternate state generating the toggle.
[0017] The latch 115 is used to latch the inverted state and thus set the next state of the switch 100 while allowing the programming at the voltage reference 110 to correctly complete. In embodiments, when the voltage pulse is received by the latch 115, the latch 115 may toggle the state of the switch from a current state to an alternate state.
For example, the latch 115 may be configured with a first state and a second state. The latch 115 may include a first voltage output pin 120a and a second voltage output pin 120b, wherein the first voltage output pin 120a is used to output a first voltage associated with a first state and the second voltage output pin 120b is used to output a second voltage associated with a second state. In response, to receiving the voltage pulse from the switch 105, the latch 115 may toggle the output from the first voltage output pin 120a to the second voltage output pin 120b, and vice versa. In embodiments, the latch 115 may be set to output a first voltage that is associated with a first state. The first voltage that is associated with the first state may be a different and/or alternate voltage than a second voltage that is associated with a second state. For example, the programmable voltage reference 110 may be set with and/or may be outputting the second voltage that is associated with the second state. In response to receiving the voltage pulse from the switch 105, the latch 115 may output the first voltage to the programmable voltage reference 110. For example, the programmable voltage reference 110 may receive the first voltage from the latch 115 through a voltage input pin 125. The latch 115 may receive the voltage pulse from the switch 105 via an input pin 130 (e.g., a CLK pin), and the latch 115 may be configured with a reference pin 135 to facilitate signaling between the latch 115 and the voltage reference 110.
[0018] The programmable voltage reference 110 may be used as a non-volatile memory. The programmable voltage reference 110 may be any element configured to permanently and persistently store a binary reference voltage. In embodiments, when the pressing of the switch 105 has ended (i.e., when the switch is released), and the switch 105 opens, the programmable voltage reference 110 may respond to the voltage pulse no longer being received from the switch 105. The programmable voltage reference 110 may detect the presence and/or absence of the voltage pulse via a switch pin 140.
In response to the voltage pulse being terminated or removed, the programmable voltage reference 110 may store a persistent version of the voltage that is received from the latch 115. For example, the programmable voltage reference 110 may begin a periodic or constant output of the voltage received from the latch 115 through the voltage input pin 125, wherein the programmable voltage reference 110 outputs the voltage through the voltage output pin 145. The voltage output through the voltage output pin 145 is the persistent logic output 150 to be used to control privacy state (or other setting) at one or more elements of the device within which the switch 100 is integrated. For example, the voltage output through the voltage output pin 145 may enable or disable one or more privacy settings (e.g, microphone, camera, an output of private user data such as location data, etc.) of the device within which the switch 100 is integrated. This signal can be used in various implementations such as removing microphone power or disabling audio data paths in the design. In response to the voltage pulse being terminated, the programmable voltage reference 110 may adjust a persistently stored voltage to the voltage that was last received from the latch 115. The state will be stored in the voltage reference and remain persistent over a power cycle. The voltage reference 110 may receive power from a power source 150 (e.g., PWR) via a power input pin 155. The voltage reference 110 may include a ground pin 160.
[0019] In embodiments, when the voltage pulse is received by the programmable voltage reference 110, a reference voltage may be output to one or more logic gates, wherein the one or more logic gates control a feature or setting based upon the output that is received from the programmable voltage reference 110. For example, the programmable voltage reference 110 may be set to output a high reference voltage or a low reference voltage, depending upon the current state that is set at the latch 115 (e.g., the voltage state at the voltage reference may be the opposite state of the state set at the latch). It should be understood that the programmable voltage reference 110 may be configured to output a first voltage (e.g., high voltage) to enable a privacy setting (or other setting) and a second voltage (e.g., low voltage) to disable a privacy setting (or other setting). After outputting the reference voltage in response to receiving the voltage pulse, the programmable voltage reference 110 may adjust a reference voltage to reflect the alternate reference voltage. For example, the programmable voltage reference 110 may adjust a reference voltage to be output from the current reference voltage to the alternate reference voltage, and the adjusted reference voltage may be output by the programmable voltage reference 110 in response to receiving a next voltage pulse.
[0020] While a privacy setting is described herein, it should be understood that the programmable voltage reference 110 may be utilized to output a singular or a persistent signal or voltage to control a variety of settings, features, and/or states.
[0021] In embodiments, the voltage pulse output from the switch 105 to the latch 115 may pass through an inverter 165 that is located between the switch 105 and the latch 115.

[0022] It should be understood that the latch 115 may switch the voltage output from the first voltage output pin 120a to the second voltage output 120b (or vice versa) in response to the voltage pulse no longer being sensed by the latch 115. For example, the [0023] FIG. 2 shows an example process 200 for transitioning from a first state to a second state. A press of a button may cause the switch 105 of FIG. 1 to generate and output a voltage pulse. The voltage pulse may be received by the latch 115 of HG. 1, and in response, the latch may toggle a switch position. A current reference voltage may be output (e.g., from the programmable voltage reference 110 of FIG. 1) in response to the voltage pulse being received. The reference voltage stored at the programmable voltage reference may be adjusted.
[0024] At 205, a voltage pulse may be generated. The voltage pulse may be generated, for example, by the switch 105 in response to a press of a button at the device.
[0025] At 210, a switch position may be toggled at a latch 115 in response to receiving the voltage pulse. For example, the voltage pulse generated at 205 may be output to and received at the latch 115. In response, the latch may toggle a switch position. For example, the switch may be toggled from a first position that outputs a first voltage from the latch to a second position that outputs a second voltage from the latch, wherein the voltages are output to the programmable voltage reference 110.
[0026] At 215, a current reference voltage may be output in response to receiving the voltage pulse. The current reference voltage may be the second voltage (e.g., the voltage currently being received from the latch 115), and the current reference voltage may be output from the programmable voltage reference 110. The current reference voltage may be output from the programmable voltage reference 110 in response to a release of the switch 105 (e.g., when the voltage pulse is no longer received by the programmable voltage reference).
[0027] At 220, the reference voltage at the programmable voltage reference 110 may be adjusted. For example, the reference voltage stored at the programmable voltage reference 110 may be adjusted from the current reference voltage (i.e., the first reference voltage) to an alternate reference voltage (e.g., the voltage received from the latch 115, in this case, the second reference voltage).
[0028] FIG. 3 shows an example process 300 for transitioning from a first state to a second state in response to a switch or button being pressed. Starting at an initial state, in response to a button/switch being pressed: a current state may be locked at a volatile latch (e.g., latch 115 of FIG. 1); an alternate (inverted) state may be output from the volatile latch to an input of a programmable voltage reference 110 of FIG. 1; a pulse may begin a programming sequence in the non-volatile element (e.g., the programmable reference 110); and the new state may be stored in the non-volatile element [0029] At 305, a device may be operating in an initial state. For example, a voltage output from the programmable voltage reference 110 may control one or more settings at one or more elements of a device within which the switch 100 is integrated.
[0030] At 310, a determination may be made whether a switch at the device has been pressed. If the switch has not been pressed, the device may continue to operate at the initial state. If the switch has been pressed, the process 300 may proceed to 315.
[0031] At 315, a current state may be locked in a volatile latch 111 For example, upon receiving a voltage pulse resulting from the switch being pressed, the latch 115 may switch the output voltage from a current (i.e., first) voltage to an alternate (i.e., second) voltage.
[0032] At 320, the volatile latch 115 may output the alternate (i.e., inverted) voltage/state to an input of a programmable voltage reference 110.
[0033] At 325, a pulse may begin a programming sequence at a non-volatile element (e.g., a programmable reference 110). For example, when the switch is released, and the voltage pulse is no longer received by the programmable reference 110, the programmable reference may output the voltage that is received from the latch (e.g., the alternate voltage) to one or more logic gates.
[0034] At 330, the new state/voltage may be stored persistently in the non-volatile element (e.g., the programmable reference 110).
